If we want some code to be executed periodically after the execution which was before is finished, we should use fixed delay (measured in milliseconds): @Component public class MyScheduler{ @Scheduled(fixedDelay=5000) public void doSomething() { // this will execute pe...

If we want something to be executed periodically, this code will be triggered once per the value in milliseconds we specify: @Component public class MyScheduler{ @Scheduled(fixedRate=5000) public void doSomething() { // this will execute periodically } }
